Engine manufacturers conduct emissions reduction research using test equipment that feeds a simulated automotive exhaust stream through candidate emissions abatement technologies. Once it has passed through the abatement system, the gas stream is analyzed to determine the efficiency with which the technology eliminates pollutants. Electronic mass flow controllers (MFCs) are used to produce the different gas mixtures that simulate the exhaust gas composition for a wide range of conditions. Precise knowledge of the independent operating parameters in an engine, the fuel formulation, and the chemical composition of the exhaust gas stream before and after the abatement technology enables the development of chemometric models that can be used to minimize engine emissions while maintaining acceptable performance.
